Isolation of bacterial strains of the genus Bacillus spp from bottom sediments of freshwater ponds of the Republic of Belarus and study of their biological properties

Abstract

The object of the study was bacterial strains of the genus Bacillus spp., isolated from the bottom sediments of freshwater ponds. The purpose of the study was to obtain producer strains of biologically active compounds of microorganisms of the genus Bacillus isolated from the bottom sediments of freshwater ponds, to study their biological properties. In the process of work, the selection and analysis of the composition of samples of bottom sediments of freshwater ponds of various regions of the Republic of Belarus and the isolation of microbial strains of the genus Bacillus from them were carried out. The morphological-cultural and physiological features were studied, the chemical composition of the metabolic products of the isolated strains (protein content, amount of amino acids, vitamins, enzymes, etc.) was established.
